Which of the following sets represents MUN?
Anuta_ua [19.1K]

Answer:

  • <u>Third choice: {3, 4, 6, 7, 9}</u>

Explanation:

<em>M ∪ N</em> means the union of the segments M and N. That is, the complete list of objects that are either in the set M or N.

The circle on the left of diagram shows that the elements inside the set M are 3, 4, 7 and 9.

The circle on the right of the diagram shows that the elements inside the set N are 4, 6 and 7.

The complete list of the numbers in either M or N is 3, 4, 6, 7, and 9 (you must not repeat the elements that belong to both sets but indicate them just once.

So, the set that represents M ∪ N is the third option {3, 4, 6, 7, 9}.

If f(x)=2x+1f(x)=2x+1f, left parenthesis, x, right parenthesis, equals, 2, x, plus, 1 and g(x)=x^2+7g(x)=x
nadya68 [22]

The value of the composite function f(g(x)) is 2x^2 + 15

<h3>How to evaluate the composite function f(g(x))?</h3>

The functions are given as:

f(x) = 2x + 1

g(x) = x^2 + 7

We have the function f(x) to be

f(x) = 2x + 1

Substitute g(x) for x in the equation f(x) = 2x + 1

So, we have

f(g(x)) = 2g(x) + 1

Substitute g(x) = x^2 + 7  in the equation f(g(x)) = 2x + 1

f(g(x)) = 2(x^2 + 7) + 1

Open the brackets

f(g(x)) = 2x^2 + 14 + 1

Evaluate the sum

f(g(x)) = 2x^2 + 15

Hence, the value of the composite function f(g(x)) is 2x^2 + 15

Ase the points (-1,1) and (1, -1) on the graph of y = 2x -3
kondaur [170]

Step-by-step explanation:

y = 2x - 3 \\ plug \: x =  - 1 \\ y = 2( - 1) - 3 =  - 2 - 3 =  - 5 \neq1 \\ hence \: ( - 1, \: 1) \: does \: not \: lie \: on \: the \:  \\ graph \: of \: y = 2x - 3. \\  \\ y = 2x - 3 \\ plug \: x =  1 \\ y = 2 \times 1- 3 =  2 - 3 =  - 1 \\ hence \: ( - 1, \: 1) \:  lie \: on \: the \:   graph \: of \:  \\ y = 2x - 3. \\  \\

Which equation can you use to solve for x?
dlinn [17]

In the given figure three angles are marked x°, 56° and 146 °

When two lines intersect they form two pairs of opposite angles. Vertical angles are always congruent, which means that they are equal.

In the figure angles x ,56 and 146 are formed on two opposite sides of the straight lines are so are vertically opposite angles and hence they are equal.

We can write this as x+56=146.

The first option is the right answer.
